[F] Trying to convince my husband to let me do amateur porn

HI all, Im under my husbands account posting a concern.

We have been talking/arguing for the last 5 days now. I know its not everyones cup of tea in a marriage to do this, but i was approached by an adult modeling agency and really want to try it. My husband is dead against it, but i think he will get off on watching me get my brains fucked out. Heres my pic https://eroshare.com/b74ncben

How can i convince him without tarnishing my marriage?
